Teaching with databases (Hunter)
Use an existing database
Build--enter data in a database
Create a new database
![Page 9: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/9.jpg)
Why use an electronic database?
Searching and sorting large amounts of data– http://www.eric.ed.gov/
Find patterns and identify trends– http://www.opensecrets.org/index.asp

Students form search strategies
Search
Sort
Draw conclusions
![Page 11: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/11.jpg)
Building a database
Teacher creates (or “borrows”) a database
Students collect and enter data–May add to a larger data set
Students use the database– Ownership
![Page 12: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/12.jpg)
Creating a database
Plan the database
Design the layout
Collect data
Enter data
Check data
![Page 13: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/13.jpg)
Why electronic databases?
Electronic databases make it easier to organize and manipulate data
Search and sort through large amounts of data
Find patterns and identify trends
![Page 14: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/14.jpg)
Using a Database
Searching– Looking for particular pieces of
information
Sorting– Purposefully reorganizing information
Question-driven
![Page 15: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/15.jpg)
Why Ask Students Questions?To find something out.To determine what students know and don't
know.To check for comprehension or level of
understanding.To provide a review of material and content.To prepare students for what is to be learned.To teach students to ask questions
(modeling).To Develop thinking skills
![Page 16: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/16.jpg)
Thought Provoking Questions
Critical Thinking and Inquiry– Collect, organize, describe, identify
relationships, interpret, evaluate, …
Databases can be “thinking” tools– Think about and experiment with data
and ideas
![Page 17: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/17.jpg)
Develop inquiry/analytical skills
Low-level questions
– requires recall of information
Higher-level questions
– require processing information
![Page 18: Agenda Announcements –Nice Job Last Week! –Presentations online Databases –Terminology –Purposes –Manipulating information –Hunter’s taxonomy –Bloom’s](https://reader035.vdocuments.us/reader035/viewer/2022062713/56649f4e5503460f94c6f41b/html5/thumbnails/18.jpg)

Bloom’s
Analysis– Breaking down information into
component parts
